SAMUEL A. NEIDICH, OF EDGEWATER PARK, NEW JERSEY TUBE AND METHOD OFFORMING THE SAME Application filed November 14, 1928. Serial No.319,213.

My invention relates to the production from celluloid, cellulosenitrate, cellulose acetate, other products of cellulose, or an suitablesubstance, of ornamental tubes whic may be used for fountain pen orpencil casings, umbrella handles, etc.

As hereinafter described, the essential feature of my invention is theformation of a pattern upon the outer surface of an inner otube, forinstance, by recessing such tube and filling the recess with visiblydifiere'nt pattern material, removing the surplusfilling material, andthus causing the surface of the tube to afford a mosaic effect. Theinner tube thus treated may be covered with an outer tube of translucentor transparent material thru which the pattern is visible.

My invention includes the various novel features of construction,arrangement, and

procedure hereinafter more definitely speci- In said drawings; Fig. I isa transverse sectional view of a tube conveniently embodying myinvention.

Fig. II is a cross sectional view of the inner tube shown in Fig. I witha diagrammatic representation of means for forming a pattern thereon.

Fig. III is a cross sectional view of said inner tube shown in Figs. Iand II, but with the filling material applied thereto.

Fig. IV is a cross sectional view of said tube shown in Fig. III, butwith the surplus filler material removed.

Fig. V is a perspective view of a fountain pen cap embodying a form ofmy invention.

Referring to Fig. I; the inner tube 1 may be formed of any suitablematerial such as above indicated, by boring a solid rod, extruding thematerial in initially tubular form, or forming the tube by rolling. aprimarily plane sheet, or otherwise. Said tube 1 has pattern recesses2formed in the perimeter thereof which are filled with a primarilyplastic pattern susbtance 3 which becomes rigid after it is applied. Forinstance, said filling pieces 3 may be the residue of any of thesubstances aforesaid which have been dissolved in a suitable solvent andapplied in a plastic condition. For instance, acetone is a suitablesolvent for celluloid and cellulose nitrate, and ethyl acetate, or amixture of alcohol and ether are suitable solvents for celluloseacetate. The latter is preferable to celluloid, because it isnoninfiammable. The outertube 5 shown in Fig. I may be formed-in anymanner above contemplated, and is rigidly connected with the inner tube1 'and the\pattern filling pieces 3. Altho I have shown dividing linesbetween the parts 1, 3, and 5; it is to be understood that when saidparts are caused to adhere by being moistened with a suitable solvent,they are integrated as if formed of one piece. For' instance, both theinner and outer tubes 1 and 5 may be formed of respective sheets ofcellu: loid rolled while moistened with acetone and preferably whilesubmerged in a bath includmg such solvent, in accordance with thedisclosures of Letters Patent of the United States No. 1,661,451 grantedto John N. Whitehouse March 6, 1928.

It is to be understood that the materials above contemplated may includeany material or coloring to render them fanciful. For instance,celluloid and the like may be clear or colored to any tint or shadeWithout inclusion of any material producing a clouded effect, but sucheffect may be produced by the inclusion of powdered aluminum or otherpowder, metallic or otherwise; for instance, what is known as fish scalepowder, suspended in clear celluloid affords an iridescent appearance tothe latter closely resembling mother of pearl. 35 I find it convenientto form the pattern upon the periphery of the tube 1 by such means asindicated in Fig. II, to wit, a die 7 having cameo pattern members 8projecting therefrom. Said die is conveniently mounted upon the holder 9which may be rocked or rotated upon its shaft 10, with said die inrolling contact with said tube 1, to form the intaglio pattern marks 2therein,,in conformity with the projections 8. As indicated in Fig. III;the pattern rev cesses 2 in the inner tube 1 may be filled with theprimarily plastic pattern material 3 of the character abovecontemplated; said pattern filler material 3 being visibly dif- 109ferent from the material of said tube 1. Said tube 1 ma be formed of oaque material, or, if trans ucent may have t e inner circumference orconvolution 12 thereof opaque, to conceal the contents of the tube, suchas black ink in a fountain pen or the metal or wood of an umbrellastick. The opaque portion of said tube 1 may be in unitary relation withthe sheet from'which such a tube may be formed or may be primarilyseparate.

Altho said attern filler material 3 is plastic when applied to the innertube 1; it quickly sets to rigid form in coherent relation wit saidtube, and the surplus portion thereof may be ground off or otherwiseremoved to leave the tube 1 with the finished outer surface as indicatedin Fig. IV. Such tubes may be used for any purpose, without the outerprotecting tube 5, but the latter enhances the beauty of the interiortube by refraction and reflection of light. The outer tube 5 may beformed upon the inner tube 1, in any way above contemplated, but, in thecompleted form shown in Fig. I, is in permanently rigid relation withthe inner tube.

Referring to Fig. V; the fountain pen cap 14 may include a tube formedas above described, wherein the pattern recesses 2 have the respectiveconfiguration of game card spots and the pattern filling material 3 iscolored to represent such spots; such a structure being desirable, forinstance, as a bridge game prize.

However, I do not desire to limit myself to the precise details ofconstruction, arrangement, or method of operation herein set forth, asit is obvious that various modificais visible therethru, and the innertube is opaque.

In testimony whereof, I have hereunto si ed my name at Burlin 11, NewJersey, this thirty-first day of Octo r, 1928.

tions may be made therein without departing from the essential featuresof my invention, as defined in the appended claims.

I claim:

1. The method of making a tube, which comprises forming an inner tube;making a pattern recess in the outer surface of that tube; filling thatrecess with visibly different material; removing sur lus fillingmaterial; and applying an outer tu e of translucant materia1,thru whichthe pattern is visible.

2. A tube comprising an inner tube having a pattern recess in itsperiphery, and a filling of visibly different pattern material in saidrecess and covered by an outer translucent tube formed of a celluloseproduct.

3. A tube formed of inner and outer tubes of cellulose products, withthe rigid residue of a primarily plastic cellulose product patternmaterial between them. 7

4. A tube as in claim 3; wherein the outer tube is translucent and thepattern material visible therethru.

5. A tube as in claim 3; wherein the inner tube is opaque.

6. A tube as in claim 3; wherein the outer tube is translucent and thepattern material
